What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Seattle, WA wrote its last area forecast discussion before this gale warning went out at Mar 30, 9:00 PM PDT, 5 hours 49 minutes earlier.
Area forecast discussion, Mar 30, 9:00 PM PDT, 5 hours 49 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SEATTLE WA
900 PM PDT WED MAR 30 2011
.SYNOPSIS...A PLUME OF SUBTROPICAL MOISTURE WILL BRING RAIN TO
WESTERN WASHINGTON THROUGH THURSDAY. RAIN MAY BE HEAVY AT TIMES
AT THE COAST AND IN THE MOUNTAINS. DRIER WEATHER IS EXPECTED FRIDAY
AS HIGH PRESSURE BUILDS OVER THE AREA. AN UPPER TROUGH WILL BRING
MORE SHOWERS TO WESTERN WASHINGTON THIS WEEKEND.
&&
.SHORT TERM...BASED ON SATELLITE AND LATEST MODELS...IT LOOKS LIKE
THERE WILL BE ONE MORE SURGE OF MOISTURE TONIGHT INTO EARLY THURSDAY
MORNING. AFTER THAT...THE SUBTROPICAL BAROCLINIC BAND THAT HAS BEEN
OVER THE AREA FOR THE LAST DAY WILL WEAKEN AND SAG SOUTH OUT OF THE
AREA WITH DECREASING RAIN DURING THE DAY. THE NAM DOES SHOW A
LINGERING PUGET SOUND CONVERGENCE ZONE INTO THE EVENING HOURS. OTHER
THAN THAT...THINGS SHOULD BE PRETTY DRY THURSDAY NIGHT AND FRIDAY
WITH A WEAK UPPER RIDGE OVER THE AREA AND LOW LEVEL NORTHERLY FLOW
DEVELOPING. AN UPPER TROUGH WILL BRING A RETURN SHOWER THREAT ON
SATURDAY BUT THIS FEATURE IS LOOKING LIKE IT WILL BE SPLITTING WITH
MUCH OF THE ENERGY MOVING INLAND TO THE SOUTH. NO UPDATES PLANNED
THIS EVENING. SCHNEIDER
.LONG TERM...PREVIOUS DISCUSSION...MODELS SHOW THE FLOW OVER W WA
BECOMING NWLY ON SUNDAY AS A RIDGE DEVELOPS OVER THE NE PAC...THEN
SHIFTS INLAND. OVERALL...A FAIRLY DRY PATTERN FOR THE REGION. THE
RIDGE FLATTENS SUNDAY NIGHT INTO MON AS ANOTHER PAC FRONTAL SYSTEM
MOVES IN. MODELS SHOW MOISTURE OVER W WA THROUGH MID WEEK WITH ZONAL
FLOW ALOFT. 33
&&
.HYDROLOGY...FLOOD WARNINGS ARE IN EFFECT FOR THE STILLAGUAMISH...
SKYKOMISH...TOLT...SNOQUALMIE...SNOHOMISH...THE MIDDLE REACH OF THE
GREEN RIVER UPSTREAM OF AUBURN...AND THE REACH OF THE PUYALLUP RIVER
NEAR ORTING. MAJOR FLOODING IS LIKELY ON THE SNOQUALMIE AND
SNOHOMISH RIVERS. FLOOD WARNINGS FOR ADDITIONAL RIVERS COULD BE
ISSUED TONIGHT OR THURSDAY MORNING...MOST LIKELY FOR OTHER RIVERS
FLOWING OFF THE WEST SLOPES OF THE CENTRAL AND NORTH CASCADES AND
OLYMPIC PENINSULA. THE FLOOD WATCH WILL REMAIN IN EFFECT FOR MOST OF
WESTERN WASHINGTON.
THE FOCUS OF THE HEAVY RAIN SO FAR HAS BEEN OVER THE CENTRAL
CASCADES...ESPECIALLY FROM THE SOUTHERN PART OF SNOHOMISH COUNTY
THROUGH THE NORTHERN PART OF PIERCE COUNTY. HEAVY RAIN WILL CONTINUE
THROUGH TONIGHT INTO THURSDAY MORNING...EASING QUICKLY BY MIDDAY
THURSDAY. THE 00Z SUITE OF MODELS ARE GENERALLY SIMILAR TO PREVIOUS
RUNS WITH REGARD TO HEAVY PRECIPITATION...BUT ARE LEANING TOWARD
SOMEWHAT HEAVIER QPF IN THE 06Z-12Z PERIOD WITH A SLIGHT TENDENCY TO
SHIFT THE AREA OF HEAVIEST RAIN FROM THE CENTRAL TO THE NORTH
CASCADES.
AS THESE DETAILS IN THE QPF ARE INCORPORATED INTO THE FORECAST --
AND THE NWRFC MAKES ADDITIONAL HYDROLOGIC MODEL RUNS -- SOME
REVISIONS TO RIVER FORECASTS AND WARNINGS ARE CERTAINLY POSSIBLE.
HOWEVER IT STILL LOOKS LIKE THE RIVERS FLOWING OFF THE CENTRAL
CASCADES WILL SEE THE MOST WIDESPREAD AND SERIOUS FLOODING...WITH A
LESSER THREAT FOR NORTH CASCADES AND OLYMPIC PENINSULA RIVERS.
MCDONNAL
&&
.AVIATION...STRONG MOIST WLY FLOW ALOFT WILL CONTINUE ACROSS THE
AREA THROUGH 18Z THU. ANOTHER SURGE OF MOISTURE WILL MOVE ACROSS W
WA TONIGHT AS A WARM FRONT MOVES INLAND. RAIN WILL DECREASE AFTER
12Z BEHIND THE WARM FRONT THURSDAY MORNING. THE AIR MASS REMAINS
MOIST AND STABLE AND WITH MOISTURE STILL BEING ADDED...CIGS AND
VISIBILITIES WILL REMAIN LOW...GENERALLY IFR/MVFR CIGS AND LOCAL
MVFR VIS.
KSEA...MOIST AIR MASS WITH PERIODS OF RAIN WILL CONTINUE TO KEEP
CIGS PREDOMINANTLY BELOW BKN-OVC020...WITH IFR CIGS BKN004-009 MUCH
OF THE PERIOD. VIS WILL BE PREDOMINANTLY VFR...WITH OCCASIONAL 2-5SM
IN -RA BR LATER TONIGHT. S WINDS 10 TO 20 KT WILL CONTINUE WITH NO
WIND SHIFTS EXPECTED. KAM
&&
.MARINE...MAIN PRESSURE GRADIENTS REMAIN SOUTHERLY TONIGHT WITH
ENOUGH SW COMPONENT TO KEEP WINDS WESTERLY THROUGH THE STRAIT. SMALL
CRAFT ADVISORIES ARE UP FOR ALL WATERS THROUGH THURSDAY EVENING. GFS
SHOWS A WARM FRONT OVER THE OFFSHORE WATERS THAT WILL MOVE ACROSS
THE AREA AFTER MIDNIGHT TONIGHT PROBABLY AROUND 09Z. ONSHORE
PRESSURE GRADIENTS INCREASE BEHIND THE WARM FRONT WITH A STRONGER W
COMPONENT. 40 KM GFS HAS SHOWS ABOUT 5 MB PRESSURE GRADIENT THROUGH
THE STRAIT AT 18Z WHILE NAM IS WEAKER AT 3 MB. 12Z 4 KM WRF-GFS HAD
WINDS JUST UNDER GALE FORCE WINDS AND NAM WAS MUCH WEAKER. WITH
WINDS BACKING OFF IN THE CENTRAL STRAIT RIGHT NOW WILL STICK WITH
THE 20-30KT SCA...THEN SEE WHAT THE 00Z WRF-GFS SHOWS BEFORE
DECIDING ON A GALE UPGRADE FOR THURSDAY.
MODELS AGREE ON THE STRONG ONSHORE FLOW COLLAPSING QUICKLY THURSDAY
NIGHT AS A SURFACE HIGH BUILDS OVER THE AREA. WEAKER ONSHORE FLOW
RAMPS UP A BIT LATE FRIDAY AS A STRONG SURFACE RIDGE FORMS FARTHER
OFFSHORE. KAM
&&
.AVALANCHE...PREVIOUS DISCUSSION...THE STRONG WEST FLOW AND WEST TO
EAST ORIENTED WARM FRONT MOISTURE WILL BE OVER THE OLYMPICS AND
CASCADES ON WEDNESDAY. THIS SHOULD CAUSE STRONG WEST WINDS AND
PERIODS OF HEAVY SNOW AND RAIN WITH A GRADUAL OR POTENTIAL SHARPER
WARMING TREND. THE HEAVIEST PRECIPITATION INTENSITIES SO FAR TODAY
AT NWAC STATIONS HAVE BEEN AT STEVENS...SNOQUALMIE AND PARADISE BUT
SEEM TO BE STARTING TO SHOW UP AT MT BAKER. SNOW LEVELS HAVE BEEN
LOWER THAN EXPECTED POSSIBLY DUE TO PRECIPITATION INTENSITIES AND
MELTING EFFECTS. THE FURTHER HEAVY SNOW...RAIN AND WARM TEMPERATURES
WILL BUILD...LOAD AND WEAKEN SURFACE AND UPPER SNOW PACK LAYERS AND
SHOULD CAUSE AVALANCHES ON WEDNESDAY. INITIAL SURFACE WET SNOW
AVALANCHES SHOULD CAUSE ENTRAINMENT OF RECENT SNOW AND MAY CAUSE
RELEASES TO DEEPER LAYERS FROM MID WINTER. LARGE AVALANCHES SEEM
POSSIBLE ON WEDNESDAY. AN EXTREME AVALANCHE DANGER IS FORECASTED FOR
THE OLYMPICS AND CASCADES NEAR AND WEST OF THE CREST ON WEDNESDAY.
THESE CONDITIONS SHOULD CONTINUE WEDNESDAY NIGHT AND MAY CONTINUE TO
SOME EXTENT INTO THURSDAY MORNING. FERBER
